Yesterday I was testing failover with rhcs5 and drbd. To test failover I simply unplugged the network cable from the server. The IP failed over like it was supposed and all the data was still there also. But when I brought the other server back on line it came up in a Secondary/Unknown state and when I did an lvscan the logical volume wasn't there anymore. So I tried setting the server to drbdadm primary all and activating the volume group "vgchange -a y VolGroup02". Still no logical volume. Which was ok because I still had the volume on the other server because of failover. Well the other server was still reading Primary/Unknown also. So I tried bringing drbd down and back up by unmounting and drbdadm down all. Then I reset the services and brought everything back up. Both server were still reading Secondar/Unknown but now the logical volume on the failover server was gone also. Has this happend to any one? Did I configure something wrong the servers were set for Primary/Primary and running a gfs2 file system.
